Approximation for Regularity of Distribution Probability of Speech Signals´ Amplitudes

The probability distribution law approximations for the criteria of maximal accuracy, simplicity of expressions, and minimal time of calculations are studied. The problem of determination of the distribution law for probability of readout of amplitudes of a speech signal in view of a modern technological level of measuring engineering is important. Other important problem is development of rather precise mathematical model of the law of the distribution obtained experimentally. Thus, the purpose of the given work is the selection of new approximation for the law of distribution of probabilities of readout of amplitudes of a speech signal
